i new java 8 , spring mvc . have java bean pojo setter , getter. spring web service using reflection maps request parameters pojo. want input validation using annotation. have requirement need read values of annotated field , check atleast 1 value provided. wrote sample code.... not sure how values assigned field. please share sample code if have:

public boolean isvalid(string object, constraintvalidatorcontext constraintcontext) {      boolean canproceed = false;     for(field field  : documentsearchrequest_global.class.getdeclaredfields())     {          if (field.isannotationpresent(validdocumentmodifieddate.class))             {                 string name = field.getname();       //iam able name of field                 system.out.println("1.name :   "+ name);                  system.out.println("2.            "+field.gettype().getname());               }     }    // method[] method = documentsearchrequest_global.class.getdeclaredmethods();    (method  method :documentsearchrequest_global.class.getdeclaredmethods() )    {        system.out.println(method.getname() );       //able name of getter , setter methods in pojo      //can u suggest how read value of particular field.. either       //getting value method??? ...    } 

you can values calling method.invoke(object, object...) first parameter class instance on method executed , second variable arguments arguments of method. in case it'll null or empty. here simple code snippet object value = method.invoke(documentsearchrequest_global_instance);
